is there a way to calculate the amount of data being sent back from a slave ? for example if all the passes required for each animated frame adds up to 400MB how much of that would a slave have to transport over a network? I ask because i wonder if there is any significant benefit for a 10 gb network card in the GPU render machine we have built.
thanks
Calculate Rendered Data passed back from slave
Moderators: ChrisHekman, aoktar
Slaves are constantly sending data to the master, because Octane is a progressive renderer and somehow the results you see in the viewport must get from the slaves to the master. So, no you can't calculate the amount of data that is send to slaves as well as received from the slaves.
A fast LAN is always good, because scene data can be sent faster to slaves and results can be received faster. The former is important when you start a new frame, the latter is important during rendering. If the connection is too slow and the (intermediate) results are too big, the master may wait a long time until the next intermediate result arrives, and with sending no new work to the slave for a long time, causing it to run out of work.
In version 3 things will be quite different, but that's how it works at the moment.
